7 MANIFOLDING SALESBOOK Filed Aug. 21, 1929 Vk v I aka/M 10 bered. \Vith this object in view my invention which the same reference characters have Patented 31, 1929 PATENT OFFICE GUSTAV RUDOLF GOMPF, OF BER-LIN, GERMANY HANIFOLDING SALES BOOK Application filed August 21, 1929, Serial No.

My invention relates to improvements in manifolding salesbooks, and "more particularly in salesbooks of the type by means of which quadruplicate copies may be made.

5 The object of the improvements is to provide a sa'lesbook of this type which can be readily handled, and in which the legends printed on corresponding sheets are always in exact register, and all the sheets are correctly numconsists in superposingan opaque and a transparent ribbon of paper or the like, and reversely folding the same back and forth upon themselves in zig-zag fashion and so, that a pair of leaves of opaque paper jointedalong th eir front edge envelop a pair of sheets of transparent paper likewise jointed at their front edge. Bythus composing the book, the numbers and legends are always printed on the sheets in a uniform way,-and errors in assembling the sheets can not occur. Further, the use of the four leaves needed for recording a sale or makingvother memoranda can be readily pulled away from the pad and torn off, after making the memorandum, and when pulling the said leaves from the pad simultaneously the upper section of the next set of leaves is bent away from the pad so that the carbon sheets canbe placed between the same.

Another object of the improvements is to provide a pad in which the carbon sheets-can be readily placed into position between the leaves of paper, and with this object in view my invention consists in jointing two carbon sheets to be used for making a memorandum in quadruplicate along one of its side edges, the fold of-the carbon sheets being parallel to the direction in which the sheets of paper are pulled from the pad, one of. the carbon sheets being preferably held in position on the pad along its upper edge. In my improved pad both carbon sheets may be coated with ink at both faces, of only one of the carbon sheets is coated'at both sides, ,while the other sheet is coated at one side only.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing in 387,467, and in Germany January 28, 1927.

" been used in all the views to indicate correof sheets.

On a base plate a a book or pad is supported which is composed of two superposed ribbons d and u of paper or the like'which are reversely folded back and forth upon themselves in zig-zag fashion, the ribbon d consisting of transparent paper, and the ribbon u of opaque paper. In the sectional elevations shown in Figs. 2 and 3 the upper leaves are slightly lifted away from the pad for more clearly showing the same and the carbon sheets placed between the same.

The memorandum is made in the usual way by writing on'the uppermost leaf of opaque paper, and for making the copies on the second, third and fourth leaf carbon sheets 10 and k are'provided, 70 being coated at both sides,twhile k is coated only at its bottom side, the coating being indicated by dotted sheet a the top face of the carbon sheet 70 reproduces the memorandum on the bottom face of the second sheet indicated in Fig. 3

by the numeral 2, the said sheet being made from transparent paper, so that the record appearing on the back' face of the sheet 1n mirror-script can be read from the'top side thereof. By the bottom face of the sheet 71: the memorandum'is reproduced on the third leaf 3. The carbon sheet 70 which has a coating only on its bottom face reproduces the lines. Thus, when writing on the uppermost within the other. In Fig. 3 thesaid leaves areshown slightly lifted away fromthe body of the pad. A pair of leaves u of opaque paper having their fold v at the front side of the pad envelo s a. pair of leaves d of transparent paper aving their fold likewise locatedat the front side of the pad. The upper leaf 2 of the inner pair is located below the upper leaf 1' of the outerpair, and the lower leaf 3 of the innerpair is located be tween the two sheets k is of carbon paper.

Along the rear side of the pada spring fastener is provided-which consists of twosheet metal strips 6 and b bent into angular formand a spring bacting thereon, the strip b bearing on the pad or book, and the strip 12 clamping the upper carbon sheet between the same and the strip 6 j The carbon sheets-k and k are jointed along their longitudinal sides by means of a fold f, thesaid fold being preferably lo cated along the right hand side of the pad.

The upper carbon sheet 70 slightly projects beyond the rear margin of the sheet k so that it can be readily clamped between the sheet metal strips 6 and b When writing a memorandum on the pad the paper ribbons d and u are assembled in the manner shown in Figs. '1 to 8, and the carbon sheets are placed between the same.

After writing the memorandum or recording the'salethev uppermost leaves 1 and 2 are folded forwardly, the third leaf 3 is slightly lifted to permit the carbon sheet k to be pulled laterally away-from the pad, and the carbon sheets are swung rearwardly into the position shown in Fig. 4, the said carbon sheets being held on the pad by means of the fastener 6 I). Now the third and fourth leaves are pulled forwardly, which leaves carry along the first and second leaves I and II of the next set. Now the pad and the leaves pulled therefrom are in the positions shown in Fig. 4'. Nowthe carbon sheet 70 automatically places itself on the third leaf III of the next set. The leaves 1-4 are separated from the leaves I and II of the pad along the line TT shown in Fig. 4, and the carbon sheet 1: is inserted below the third leaf III which for this purpose is slightly lifted from the pad. After placing leaves I and II on the carbon sheet is. located on the top of the pad the book is ready for further I claim: j w 1.
